(04-28) 19:30 PDT -- The Warriors' coaching search officially began Thursday, a day after Keith Smartwas informed that his services wouldn't be retained for the 2011-12 season.

But not so fast. There's plenty more in the works before they get to that.

Team sources said more movement among the Warriors' staff is expected as soon as today, and general manager Larry Rileyreiterated that a head coaching move alone won't be enough to turn the franchise into a playoff contender.

The other immediate moves are expected to be among the team's support staff, possibly player development, strength and conditioning and/or training. Sources weren't ready to name names because some of the staff had not yet been informed.

The rest of the moves will deal with the roster itself, which Riley admitted wasn't good enough to reach the playoffs this season. He said he had a glimmer of hope when the Warriors headed into the All-Star break with an impressive win at Utah to get to three games under .500.

The Warriors returned from the break with a 2-7 stretch, during which they played some of their worst ball and showed major personnel flaws. Riley, who was more willing to say the roster flaws were his fault than to talk about Smart's on-court failures, assesses the team's needs as a center, a big guard and a legitimate sixth man who will probably be a wing player.

"I think next year we should be in the playoffs," Riley said. "We're not (a playoff roster) right now. It will be a playoff roster."

In what hinted at a major change in philosophy, Riley noted that all of the potential additions have to be better defenders. He even seemed open to slowing his preferred uptempo style offense.

"That doesn't mean I have to go get a defensive guru to coach," Riley said. "Our defense has to improve, but that's not necessarily the model for the coach. ...

"We do like the uptempo game, because the roster is geared that way. That could change, if we change the roster as well as the coach."
